PROCESS AND APPARATUS FOR MAKING METAL-COATED PAPER STRIPS.

Specification of Letters Patent.

Patented April 17, 1906.

To all whom it may concern:

Be it known that I, GEORG BRAUNLEIN, a subject of the Kin of Bavaria,and a resident of No. 35 Wirt strasse, Nuremberg, Bavaria, Germany, haveinvented certain new and useful Improvements in Processes and Apparatusfor Making Metal-Coated Paper Strips; and I do hereby declare thefollowing to be a full, clear, and exact descri tion of the invention,such as will enable ot ers skilled in the art to which it appertains tomake and use-the same.

My invention relates to apparatus for preparing metal-coated paper.

One utility to which my device is very generally applied is preparingold or silver coated paper, the gold or si ver being used for signs andgilding or like ornamental purposes. It is well known that insign-writing it is customary to pick up the gold leaves, which arepacked between sheets of paper, with a hair-brush and apply the sheetsto a prepared surface, constituting the sign-body or part to bedecorated. A great waste of gold-leaf results from this process for thereason that it is impossible to pick up the exact width of leafcorresponding to the area of surface to which it is to be ap lied. Insign-painting the letters are blocke out upon the glass or othersurface, to which is previously and subsequently applied a suitableadhesive solution, such as varnish. In applying the gold-leaf to theblocked surface, the sign-writer completely covers the letters with goldor the like and then sha es the letters in accordance with the originablocking. In forming the letter A, for instance,the gold coverin thecentral or open space of the letter wou d have to be cut away entirely,and this material is thrown aside as waste. It has been proposed,therefore, to mount the gold-leaf upon strips of paper wound u on smalldisks and to apply the gold or the ike from a disk of a widthcorresponding closely to the blocked area u on which the gold is to beapplied. Strips 0 this nature have heretofore been .prepared. by coatina given Width or strip of paper with goldeaf or like metal and windingthe same upon a solid roller and subsequently subdividing the roller andthe coated paper thereon into disks of various widths, the subdivisionbeing effected by mounting the roller in a sawin or cutting machinehaving knives or saws. 'Fhis method of preparing metal-coated aper hasobvious disadvantages, inasmuch as a cuttingtool adapted to operate uponpa or is not at all adapted to operate upon woo and as the saws operatinupon wood are necessarily relatively thic a great waste of material issustained in subdividing the roller. Further, it is quite impossible inapplying the known processes to successfully turn out disks or strips ofaper of narrow width, since the knives in subdividing the roller carryoff portions of the gold, as the latter cannot be pressed so tightlyupon .the paper as to withstand the severe frictional contact to whichit is subjected by the saws or knives. To this end I propose to Wind themetal-coated paper upon a receiving-roller made up of a plurality ofseparate disks of equal or varying widths and subsequently cutting thewound pa er by any suitable means, the distinct dis s being thereaftereasily separated. By means of my improved device relatively thin knivesor saws ma be used, since the latter are not emplo ed or cutting thematerial of which the r0 ler is composed, but are used merely to cut theaper. By this improved means I am ena led to manufacture disks ofmetal-coated paper of any desired width in a rapid and inexpensivemanner.

My invention will be more fully described in connection with theaccompanying drawings and will be more particularly pointed out in theappended claims.

In the drawings, Figure 1 represents in side elevation a machineembodying the main features of my invention. Fig. 2 reprFesents a planview of the device shown in i 1. Y 'Iiike characters of referencedesignate similar parts throughout the different figures of thedrawings.

My invention, as shown, consists generally of a base a, on which ismounted mechanism carrying a paper-feeding roller, a receivingroller,and means for applying to one side of the paper as it passes from thefeeding to the receiving roller a suitable non-adhesive material. Thefeed-roller w, as shown, is mount ed in collapsible bearing-standardscomprising stationary uprights C, having hinged extensions b, connectedat their free ends to a fixed standard a by contractile springs b.

Means are provided whereby the supply-roller m is removably mounted inthe extension b and in a manner to permit lateral adjustment and directthe paper toward the receivingrollcr in alinemcnt therewith. Said meansdesirably consists of threaded thumb-screws 0, having threaded bearingsin the arms I) and impinging with their inner ends on the supply-rollerat the axis thereof. The inner ends of said screws are conical in formand fit in complements-1 recesses in the roller. By reference to Fig 2it will be obvious that the thumb-screws may be turned to adjust theroller axially in any desired horizontal position. When it is desired toinsert a new su ply of paper, the arms I) are swung outwardly from thestandard against the action of the springs b.

- As the paper travels from the supply-roller to the receiving-roller itis guided by a table 1, pivotally mounted on standard 1*. Beyond saidtable it is engaged on its lower side by a roller f, sunk in a trough I.Said roller is journaled in standards I and is provided with a wheel orsheave i at its outer end. Said trough I is adjustably mounted on astandard 7. and is secured thereto by means of a collar I and athumb-nut I. The trough I desirably contains non-adhesive material, withwhich one side of the paper strip is dusted or coated. Powdered bolushas been found to perform the function desired and permits the paper'tobe tightly Wound without collecting the gold-leaf.

The paper passing from the roller f to the receiving-roller g isprovided with strips of metalq, which are desirably laid thereon by handor automatically fed, said strips being desirably overlapped in order tocoat the strip of paper with a continuous strip of metal. Thereceiving-roller, as herein shown, consists of a plurality of separatedisks 0 0 0 0 0" 0 threaded upon a spindle g and which are clamped intight contact thereon against a shoulder a by a nut p. Said spindle isremovably secured in cone-bearings which permit of lateral adjustment ofthe receivingroller. Below the disk roller is mounted a shaft 2,carrying on one end an operatingcrank .2 and a gear-wheel 2 adapted tomesh with a gear 2. Said operating-shaft is provided on its opposite endwith a wheel or sheave 2 in alinement with the wheel F. A rope is orother suitable power-transmitting belt is trained about .said wheels,and as the crank 2 is turned the roller f is rotated in a directionopposite to the direction of travel of the paper. Said roller f ispreferably covered with felt or similar material in order that thenon-adhesive material or bolus may easily adhere and may be carriedround by theroller and dusted or coated upon the under side of the stripd. In order that the paper and metal wound upon the disk roller may notbe wrinkled at any point, a springactuated press er-roller Z isprovided, which is rotatively mounted in a frame 1 secured to fixedstandards 1 Sand frame is connected by a contractile spring a to theframe m, which serves to hold the presser-roll Z tightly engaged withthe receiving-roll. When the diskor receiving roller is being wound withpaper and metal, it will be obvious that the metal q, which, as shown,rests on the top surface of the strip, will, while being wound upon theroller engage the paper; but inasmuch as the lower side of the paper isthoroughly coated with the powdered bolus it will not adhere to themetal.

When the disk or receiving roller is full, it is removed from theapparatus herein shown and is mounted in a cutting-machine, the knivesof which are adjusted or s aced apart a distance equal to the width of te disks 0 to 0 knives have passed through the aper they will, ifslightly further advanced serve to separate the disks, whereu on thelatter may be slid off from the spin e and packed for shipment. It willbe obvious that the disks 0 to 0 may be of different Widths, so that thegold-leaf may be a plied economicall to any prepared surface with theleast possib e waste, the width of the surface and disk selected beingpractically the same.

While I have herein shown and described a specific embodiment of myinvention, it will be obvious that the same may be materially alteredwithout departing from the spirit of the invention, and I therefore donot Wish to Ee limited to the precise construction shown;

What I claim, and desire to secure by Letters Patent, is

1. The process or preparing metal-coated fabric for ilders use whichconsists in applying a p urality of strips of metal foil of varyingwidths, to one side of a plurality of strips of fabric, then'applyingmaterial capable of preventing the adhesion of said foil to said stripsof fabric, then subjecting the fabric to pressure and simultaneouslywinding said strips of fabric and foil upon cores Blame I It willreadilybe seen that when the IIO corresponding in width to the fabric woundmeans for rotating said roller, means for feeding to said roller a stripof aper rovided on one side with a thin layer of meta and coated on theopposite side with powdered bolus or the like, and a tightening-rolleryieldingly held in enga ement with the paper wound upon said dislroller.

3. An apparatus of the class described comprising a roller rotativelysupported and composed of a plurality of separate disks, a s indle onwhich said disks are threaded, c amping-nuts for securing said disks inposition upon the spindle, a spring-actuated pressure-roll for said diskroller, a collapsible standard carr ing a su ply or roll of papercarried on sai standar a coating-roller rotatably mounted andlocated'between said disk roll and su ly-roller, a trough for saidcoating-roll an 1n which the latter is sunk, said coating-rollerengaging the lower face of the paper as the same is fed to the diskroller,

and a pivotally-mounted table guiding said 10 paper on itspassage fromthe supply-roll to the coating-roll.

In testimony whereof I affix my signature in presence of two Witnesses.
